This code is written to run on the High Performance Computer (HPC) If running on a computer locally, you need render_test.m, Conditions, Mappings, .hdr (light field) and .dae (3D model) files.
gk_hpc_conf.m is required to configure the Mitsuba on HPC. run-matlab.pbs is for sending jobs to HPC.
Ben: You can see in the Mappings file all other ways I tried to change the camera setting. You can use either .dae files to render.
